JOURNAL BOX STRUCTURE Filed Jan. 2'7, 1941 2 Sheets-Sheet 2 INVENTOR 771eoa ore F. Wale! ATP'RNEY Patented Dec. 16, 1941 UNITED STATES ATENT OFFICE JOURNAL BOX STRUCTURE Theodore It. Weber, Latrobe, Pa., assignor' to American Locomotive Company, New York, N. Y., a corporation of New York This invention relates to journal box structures for railway vehicles, and more particularly to the lid hood and supporting pintle therefor.

An object of the invention is to provide a pintle, securely held in place and, by simple means, rendered easily assembled and disassembled.

A further object is the devising of means rendering the pintle non-rotative relative to the lid hood and a lid hood having improved means for support of the hood by the pintle, providing maximum bearing surface against the pressure of the lid-closing spring.

Other and further objects of this invention will appear from the following description, the accompanying drawings and the appended claims. I

Referring to the drawings: Figure l is a plan view of a pintle comprising the present inven tion in association with the box lug, shown in dot and dash lines, and the hood sides, shown fragmentally and in section; Fig. 2 is a section on the line IIII of Fig. 1, the lug not being shown; Fig. 3 is a view similar to Fig. 1, showing a slightly modified pintle and a slightly modified hood; Fig. 4 is a section on the line IVIV of Fig. 3, the lug not being shown; Fig. 5 is a view, similar to Fig. 1, showing further modified hood sides and a different type of pintle; Fig. 6 is a section on the line VIVI of Fig. 5, the lug not being shown; Fig. 7 is a fragmentary front View of the hood, showing an improved pintle-retaining orifice; Fig. 8 is a section on the line VIII-VIII of Fig. 7; Fig. 9 is a side View of the portion of the hood of Fig. 7; Fig. 10 is a view similar to Fig. 5, showing a modified pintle and a modified hood; and Fig. 11 is a section on the line XI-XI of Fig. 10, the lug not being shown.

The invention, while not necessarily confined to any particular type of journal box or journal box lid structure, is nevertheless especially suitable in connection with well-known types of lid structures for open. faced boxes, the structure comprising a lid for closing the open face of the box, the box having an orificed hinge lug, a hood flexibly connected to the lid for support thereof, and having orificed sides, a pintle supported in the lug orifice and extending into the hood orifices for support of the hood, and a spring between the hood and lid, exerting inwardly directed pressure upon the lid to hold it closed, and outwardly directed pressure upon the hood. This outwardly directed pressure upon the hood causes the rear wall portions of the hood ori-.

adjacent face of the pintle causing the pintle at its forward portion to exert outwardly directed pressure on the adjacent face of the lug orifice. Thus these faces respectively support the hood and pintle at their respective portions against the outward force of the spring. There is considerable wear between these portions of the hood orifices and the adjacent faces of the pintle due to the constant vibration of the hood during running of the railway vehicle, which wear it is an object of the present invention to minimize by providing means for increasing the bearing surfaces of these hood orifice portions andmeans for preventing the pintle from rotating relative to the hood.

In the accompanying drawings only such parts of the journal box structure are shown as are necessary for a clear understanding of the invention.

Referring to the embodiment of the invention shown in Figs. 1 and 2, the box hinge lug is indicated by the reference numeral I and the hood generally by the reference numeral 2, only the sides 3 and 4 of the hood being shown and these being shown fragmentally.

The pintle is indicated generally by the reference numeral 5. It comprises a body 6 and a head 1. The body is supported in an orifice 8 formed in th lug, and is supported at its forward portion 9 by the lug against the force of the aforementioned spring (not shown) in the usual manner. The end portion I!) of the body extends in an orifice II formed in the hood side 4 supporting the hood at this side. This side is supported at the portion I2 by th pintle at its rear portion against the force of the aforementioned spring.

The other hood side 3 is provided with an orifice I3 offset from the pintle body 6. The head I extends in orifice I3, supporting the hood at this side. This side 3 is supported at the portion I4 by the head at its rear portion against the force of the aforementioned spring. This portion I4, due to the offsetting of the orifice l3 and head I, is disposed opposite the adjacent end of the body at the portion I5 thereof, thereby preventing the pintle from moving in a direction toward the offset orifice I3. The head I is provided with a front offset portion I6 within the orifice I3 disposed opposite the adjacent end of the lug, preventing movement of the pintle in a direction away from the offset orifice. The orifice I3 extends forwardly beyond the portion I6, providing a space I'l'. Thus the pintle is held fices to exert outwardly directed pressure on the .5 against axial movement in either direction by simple means, no securing means being required at the end of the body opposite to the headed end.

By moving the side 3 relative to the pintle rearwardly, which may be accomplished by slightly tilting the hood, the tolerances being sufficient to permit this, the portion I 4 may be moved sufiiciently away from the head 1 to clear the body 6 so that the pintle may be withdrawn from and inserted into the orifices.

The orifice I3 is elongated and the head 1 disposed therein is also elongated as shown in Fig. 2. Thus th pintle is prevented from turning relative to the hood, thereby minimizing wear between the hood and the pintle. The body 6 rotates relative to the lug when the lid is opened and closed, but the bearing surfaces here are so great in comparison to those at the'hoodthat there will be no appreciable wear caused by such rotation or by vibration or chatter when the 10- comotive is running. The head I exterior to the side 3 is enlarged to provide a forwardly extending lip 18 that covers the space I1, thereby preventing foreign matter from entering the hood.

Figs. 3 and 4 show a slight modification. The sides 3', 4, are each provided with a flange I9 embracing the orifices II and I3, thereby adding width to the bearing surfaces between the orifice H [and end portion l, and between the orifice l3 and the head 1, which head within the orifice I3, is made correspondingly wider than the head 1 within the orifice l3. Otherwise the embodiment of Fig. 3 is similar to that of Fig. 1.

Figs. to 9, both inclusive, show still another embodiment. Here the orifice l3 of the hood 2 is similar to the orifice H, each being circular so that the pintle may be inserted in and withdrawn from the orifices in the usual manner. The hood sides 3", 4" are provided respectively with outwardly extending flanges 20, 2|, embracing the orifices. The flanges are integral with their respective hood sides and are disposed at the rear portions of and extend only part way about their respective orifices.

The hood 2 may be cast or made of pressed sheet metal. Where it is made of pressed sheet metal the flange 20 and orifice I3" are made as follows: Side 3 is cut through to form an arcuate forward portion 22 for the wall of the orifice [3 which extends to the ends of the flange 20, and the material of the side adjacent and rearwardly of the cut portion is forced outwardly thereby providing the remainder of the orifice wall and also the flange 2i], that is to say the flange 28 is made from the material that was formerly part of the side 3 within the bounds of the orifice. This enables a flange to be formed, due to the fact that it only partly surrounds the orifice, of maximum width and therefore of maximum bearing surface which minimizes the wear between the flange and pintle. While the major portion of this material is used in forming the flange, in practice a relatively small portion may be removed to enable the outer edge of the flange to be made of suitable contour. The orifice H and flange 2i are formed in a similar manner.

The head 1 may be adjacent either side of the hood. It is shown in the present instance adjacent the side 3 extending in the orifice [3", more correctly the body 6" extends in this orifice with the head in engagement with the flange 2B. The head 1 extends forwardly to provide a lip l8 exterior to and overlapping the side 3". The

lip extends rearwardly into the space between the oppositely disposed end portions 23 of the flange 20. This prevents the pintle from turning relative to the hood, thereby minimizing wear between the pintle and the hood.

The lip l8 prevents the pintle from moving in a direction away from the side 3 and means are provided which may be any desired or wellknown means for preventing the pintle from moving in an opposite direction. In the present instance the end portion ill" of the body of the pintle is provided with a longitudinally extending V-shaped groove forming two branches 24 and 25. One of the branches, as the branch 25, is made the longer and of bendable metal, the branch 25, shown in dot and dash lines, being the position assumed thereby to permit the pintle to be inserted into or withdrawn from the orifices, and the branch 25, shown in full lines, being its position when bent after the pintle is inserted in the orifices, this position preventing the pintle from moving in a direction away from the side 4.'

Figs. 10 and 11 show another modification employing flanges 2t, 21, a head 1" engaging the flange 26, and a lip 18 overlapping the side 3". These parts are similar to the correspond ing parts of the embodiment of Fig. 5 and operate in a similar manner to keep the pintle from turning relative to the hood and from moving in a direction away from the orifice l3'. The embodiment of Fig. 10 differs from that of Fig. 5 in that the pintle 5" and the orifice I3' are respectively similar to the pintle 5 and orifice [3 of the embodiment of Fig. 1 except that the pintle 5" does not have the offset portion I6 of the head present in the embodiment of Fig. 1 as this is not necessary in the embodiment of Fig. 10. The movement of the pintle 5' from and insertion into the orifices is accomplished in a manner similar to the embodiment of Fig. 1.

While there have been hereinbefore described approved embodiments of this invention, it will be'understood that many and various changes and modifications in form, arrangement of parts and details of construction thereof may be made without departing from the spirit of the invention'and that all such changes and modifications as fall within the scope of the appended claims are contemplated as a part of this invention.
